LEATHER-GAG E.

SPECIFICATION forming part Of Letters Patent NO. 621,518, dated March 21,1899.

Application filed April 4, 1898. Serial No. 676,294. (No model.)

To all whom it'may concern.-

Be it known that I, ALBERT J. BRUCE, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvementsin Leather- Gages; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple, economical, convenient, and efficient tool for gaging leather. It therefore consists in certain peculiarities of construction and combination of parts hereinafter set forth with reference to the accompanying drawing and subsequently claimed.

The drawing represents a partly-sectional side elevation of a leather-gage in accordance with my invention.

Referring by letter to the drawing, A represents .a shell constituting the handle portion of the herein-described tool and a casing for certain parts of the same, said shell or casing being shown as having a detachable side 13, held in place by conveniently-arranged rivets or screws.

The shell A and its detachable side B are preferably cast metal, the former being in one piece, with an end yoke O at a right angle thereto and a segmental plate D, the latter being sprung between said shell and the yoke. Cast with or otherwise delineated on the segmental plate are .graduations and index characters of a scale by which to measure weight of leather in proportion to its thickness and a predetermined area of surface.

The yoke C has one end thereof provided with a flat lug Z2 of sufficient areato have good contact with leather to be gaged, and this lug is directly opposite a fiat head 0 on the outer end of a spring-controlled slide that has reciprocation in the shell A aforesaid.

A pivotal pointer normally occupies a 1ongitudinal slot in the shell A, and incidental to operation of the slide this pointer is caused to traverse the scale aforesaid, and provision may be had for a certain degree of outward movement on the part of said slide before the pointer comes into operation.

The slide E herein shown consists of a bar having a widened and longitudinallyslotted portion cl and a right-angled rear extremity e, the latter being extended out through a longitudinal slot f in the shank-or' the contractive force of this spring operating to automatically return the aforesaid slidebar to normal position after the. same has been pushed out by pressure against its outwardly-projecting right-angled rear end.

The scale-pointer G herein shown has-pivotal connection with the slide-bar and is provided with a lug m, that engages a bayonetslot n in a plate H Within the forward shell portion of the tool. When the slide-bar. is moved forward against resistance of its controlling-spring, the lug m of the pointer will for a time move in the horizontal portion ,of the bayonet-slot with which it is engaged, and therefore said pointer will not have swing in opposition to the scale aforesaid until said lug enters the vertical portion of said bayonet-slot, this swing being proportionate to the thickness of leather between the yokelug b and slide-bar head 0 above specified. When this operation takes place, the portion of the pointer with respect to the scale will show the number of ounces in a square foot of leather having thickness equal to the dis tance then existing between the yoke-lug and slide-bar head.

The yoke O is of such dimensions as to per-- While I have shown and particularly described one form of a leather-gage in accordance with my invention, the mechanical details of the same may be somewhat varied in practice without departure from What I seek to cover. 7

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- I 1. A leather-gage comprisinga shell having an end yoke and a segmental scale, the latter being graduated to measure weight of leather in proportion to its thickness and a predetermined area of surface, a spring-controlled push-slide guided in the shell longitudinally thereof opposite a terminal of the yoke, a scale-pointer in pivotal connection with the slide, a lug on the pointer, and a stationary slotted plate in said shell engaged by said lug, deferred operation of the pointer being had by travel of its lug in the plate-slot during the time said slide has a predetermined degree of outward movement.

2. A leather-gage comprisinga shell having an end yoke, one terminal of which is provided with a flat inner lug, a segmental scale sprung between the shell and yoke and graduated to measure weight ofleather in proportion to its thickness, and a predetermined area of surface, a spring-controlled push-slide guided in the shell longitudinally of the same and provided with a fiat outer head opposite the yoke-lug, a scale-pointer in pivotal connection with the slide, a lug on the pointer, and a stationary slotted plate in said shell engaged by said lug, deferred operationof the pointer being had by travel of its lug in the plate-slot during the time said slide has a predetermined degree of outward movement.

8. A leather-gage comprising a shell having an end yoke and a segmental scale, the latter being graduated to measure weight of leather in proportion to its thickness and a predetermined area of surface, aspring-controlled slide-bar guided in the shell opposite a terminal of the yoke and having a right-angled rear end engaging a slot longitudinally of said shell, a scale-pointer in pivotal connection with the slide, an adjustable track in the aforesaid shell provided with a vertical depression, and a track-supported lug on the pointer, this lug being brought into engagement with the track depression at a predetermined point inthe outward movement of said slide.

4.. Aleather-gage comprising a shell having an end yoke and a segmental scale, the latter being graduated to measure weight of leather in proportion to its thickness and a predetermined area of surface, a spring-controlled push-slide guided in the shell longitudinally thereof opposite a terminal of the yoke, a

scale-pointer in pivotal connection with the slide, a lug on the pointer, and a stationary lug-track in said shell provided with a vertical depression, deferred operation of the pointer being had by travel of its lug on the stationary track during the time said slide has a predetermined degree of outward movement.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in

the county of Milwaukee and State of VViscousin, in the presence of two witnesses.

ALBERT J. BRUCE.
